Fraunhofer ISI researches the topic area "Energy transition" in the Competence Centers Energy Technology and Energy Systems as well as Energy Policy and Energy Markets. This facilitates a comprehensive and holistic view of the energy transition from very different perspectives: Economic and technological aspects as well as ecologic and social factors are examined. All relevant actors which are involved – from political and economic decision makers to the general public – are also included.  


The research of the two Competence Centers on the issue "Energy transition" can be divided into four large multi disciplinary cross-sectional fields: policy advice, model-based analysis of the German and European energy systems, social aspects of the energy transition as well as the international dimension of the energy transition.


Policy advice

Fraunhofer ISI with its expertise provides specific advice to political actors on the "energy transition". Important aspects are for example strategies and in-struments to expand renewable energies as well as the sustainable and effi-cient use of energy. However, policy advice also deals with issues such as the achievement of climate political objectives, security of supply or maintaining and expanding industrial competitiveness in the context of the energy transi-tion. Furthermore, scenarios for the future development of renewable energy technologies are developed and energy political instruments based on empiri-cal and model-assisted processes are investigated.

Model-based analysis of the German and European energy system

The energy transition leads to a radical change of energy systems and results in lasting impacts on the environment, economy and society. Fraunhofer ISI conducts model-based analyses of the German and European energy system and also examines the energy supply and energy demand side up to the time horizon 2050 in order to facilitate that all actors involved in the energy transi-tion address the changes at an early stage. For example with the aid of energy-system-models the design of the electricity markets can be optimized and op-tions for the integration of renewable energy technologies into the energy sys-tem can be analyzed. In addition, in the research projects of the Institute sce-narios to assess the future energy demand in the long-term and its possible impacts on countries, regions and sectors are developed.

More information on the model-based analyses can be found on the web sites of the two energy system models enertile and Forecast / eLoad.

Social aspects of the energy transition

The energy transition and achieving all connected environmental and climate objectives can only be successful as a project relevant to society as a whole when all relevant actors participate. In addition to the political will and the ac-tive participation of industry citizens also make a significant contribution to the energy transition. For example the scientists of Fraunhofer ISI investigate in user studies the acceptance of electric mobility or develop interactive planning instruments to increase the social acceptance of wind energy projects.

International dimension of the energy transition

The organization and implementation of the global energy transition is increas-ingly relocated onto the supranational level. For this reason political strategies, laws and regulations are embedded more and more into an international framework and Fraunhofer ISI provides advice for its design. In addition Fraunhofer ISI investigates for individual countries and regions, international organizations and enterprises for example the effectiveness of adopted measures in areas such as renewable energies, energy efficiency, climate pro-tection or energy management and works out recommendations and options for action.
